Abstract
An electrode lead comprises a tubular lead body, an electrode supported by the lead body, a rotatable member, a deployable member and a deployment mechanism. The rotatable member is contained within a distal end of the tubular lead body. The deployable member is attached to the rotatable member and comprises a tissue anchor. The deployment mechanism is configured to drive the deployable member along a central axis and out the distal end of the tubular lead body responsive to rotation of the rotatable member about the central axis. In one embodiment, the deployable member does not rotate about the central axis with the rotation of the rotatable member.
